Update STM32F767zi firmware through system bootloader via USB-stick

Hi,

I saw that it is possible to flash firmware via the Cube Programmer and the System Bootloader. Is it also possible to update the device through the system bootloader from a USB stick?

Also, does someone have a suggestion where I can find more information about the build- in bootloader other than the application note? 

Thank you very much

No it doesn't support such a mode.

There's a FW Upgrade / IAP example for several F4 and F7 boards using the USB MSC HOST and FatFs. Similarly you could create something to use a MicroSD card, or Ethernet.

The ISP has very finite modes of operation, not all eventualities on all boards.. Use AN2606 as controlling..

Tips, Buy me a coffee, or three.. PayPal Venmo (See Profile) Up vote any posts that you find helpful, it shows what's working..
